Helen Lin continues to prove she has no limit when it comes to navigating the open water. Earlier this month, Helen became the first person to make the 18-mile round trip swim from Nantasket Beach in Hull to Northeastern University's Marine Center in Nahant. Helen took a whopping 10-minute break in Nahant before heading back to Nantasket.
